ASSESSESSMENT OF NO2 AND PM2.5 IN ETSAKO EAST USINGSENTINEL-5P AND GOOGLE EARTH ENEGINE FROM2019-2024

This is carried out to assess the concentrations of Nitrogen dioxide (NO2) and Particulate matter (PM2.5), in Etsako East Local Government Area. Secondary data collection method was employed for the assessment. Levels of Nitrogen dioxide (NO2) and Particulate matter (PM2.5) were extracted biannually from Google Earth Engine using information from Sentinel-5-P satellite data (COPERNISCUS/5SP/NRT/L3_). A comparison of the levels of Nitrogen dioxide (NO2) and Particulate matter (PM2.5) was done biannually from the year 2019 to the year 2024 in Etsako East LGA. Results showed that the annual mean concentrations of Nitrogen dioxide (NO2) ranged from 0.000048mol/m2
to 0.000062mol/m2, the highest and lowest concentrations were found in the first half of 2021, and the first half of 2022 respectively. Particulate matter (PM2.5) ranged from -0.2341 to 0.4357. The highest and lowest concentrations
were found in the first half of 2021, and the second half of 2022 respectively. This
condition as an implication of irritating airways and exacerbating respiratory conditions on the residents. Government should play their role in policy making soas
to enforce a cleaner production process by the cement factory located there. GIS applications should also be employed and used to foster air quality and check for any deviations.
